水陆两栖飞机结构密封防水与排水设计

Design on Pressurize and Drainage of Amphibious Aircraft Structures

目的确保水陆两栖飞机在日历寿命周期内不会因积水问题造成严重腐蚀。方法根据水陆两栖飞机特殊的使用环境特点,综合笔者多年从事飞机腐蚀防护设计工作的经验,对结构密封防水和排水设计进行全面分析和论述。结果提出了水陆两栖飞机结构密封防水和排水原则,给出了水陆两栖飞机典型结构防水和排水的具体措施。结论已在大型水陆两栖飞机中应用,并顺利通过了水密试验验证。

Objective To ensure that serious corrosion would not happen due to hydrops in the amphibious aircraft in the calendar life cycle. Methods According to the characteristics of special using environment of amphibious aircraft, in combination of the author＇s years of design experience on the aircraft corrosion protection, waterproofing and drainage design of sealing structure were analyzed and discussed comprehensively. Results The principles of sealed waterproof and drainage of the amphibious aircraft structure were proposed, detailed measures were given of amphibious aircraft typical structure of waterproof and drainage. Conclusion The structure was applied in large amphibious aircraft and passed the water tightness test for verification smoothly.
